Population genetics of the fish tapeworm Wenyonia virilis (Caryophyllidea: Caryophyllaeidae) and its fish host Synodontis schall
The presented thesis consists of three papers/manuscripts (one published, one under review, one manuscript) on population genetic aspects of a host-parasite model, caryophyllidean tapeworm Wenyonia virilis and mochokid catfish Synodontis schall, in recently separated drainage basins, Lake Turkana and the Nile River. Three main topics are addressed herein: (i) intra- and inter-population genetic variability in and among hosts and parasites, (ii) comprehensive assessment of host model taxonomic status using multiple approaches, (iii) comparison of parasite intraspecific phenotypic with population genetic pattern. Two different genetic markers were applied to address these topics mtDNA (coxI) and whole genome scanning method (AFLP).

Phylogenetic relationships of trematodes of the family Heterophyidae were examined using sequences of complete ITS2 and partial (D1-D3 region) LSU rDNA. The results indicate possible paraphyly of the family Heterophyidae because two heterophyid species, Psedexorchis major and Cryptocotyle lingua, appeared among families Cryptogonimidea nad Opisthorchiidae. The genus Ascocotyle apears paraphyletic because Pygidiopis macrostoma forms a sister clade with members of the subgenus Ascocotyle. Molacular data indicate necessity of some taxonomic changes but are in general congruence with the current clasification of the superfamily opisthorchioidea.
